Linda Deming of Pownal is about to get an amazing gift from a complete stranger.

Deming was so desperate for a kidney transplant that she advertised from her car and posted signs along the road looking for help in September.

“I think it’s unbelievable,” she said. “It chokes me up when I think somebody would do that for me.”

Her signs are now stacked up in her garage after dozens of people answered her call for help.

“There’s so much good out there and it humbles you, and it has given me a whole different outlook on everything,” Deming said.

At least 50 people responded to her, and she eventually found two perfect matches. On Thursday, Deming got the green light from her doctors and she’s getting a new kidney.

“(It’s a) roller coaster of emotions. I’m scared. I’m excited. Disbelief. I don’t know what I’m going to do every Monday, Wednesday and Friday if I don’t have to get up and go sit in dialysis. You know? It’s going to be life-altering. I’m real excited,” she said.

Her donor is Amber McIntyre, a 37-year-old married mother of four from Kenduskeag who works as a waitress in Bangor.

McIntyre saw Deming’s story on Facebook and decided to do what she teaches her kids to do.

“We do the right thing because it’s the right thing, and I really felt like this was the right thing. And what better way to show them what that means than to just do it so they can learn?” McIntyre said.

Deming said she hopes her story will help raise awareness and prompt more people to become donors.

“Anybody that’s watching this that can see how excited I am to be off of that machine, call Maine Transplant. Offer your kidney. You can live just fine with one,” she said.

Deming said her surgery is scheduled for next Tuesday morning at Maine Medical Center. She will meet McIntyre in person for the first time the night before.
